Quaternary extinction event: 640,000, 74,000, and 13,000 years ago: Unknown; may include climate changes, massive volcanic eruptions and Humans (largely by human overhunting) [4] [5] [6] Neogene: Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene disruption ...
In May 2020, studies suggested that the causes of the mass extinction were global warming, related to volcanism, and anoxia, and not, as considered earlier, cooling and glaciation. [7] [8] However, this is at odds with numerous previous studies, which have indicated global cooling as the primary driver. [9]
The causes of these extinctions are varied — land-use change, habitat loss, deforestation, intensive farming and agriculture, invasive species, overhunting and the climate crisis — but all ...
Multiple notable earthquakes have struck the United States this year, including a powerful quake in California and a historic event on the East Coast earlier in 2024.. Strong earthquakes can lead ...
An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is ...
Movement of tectonic plates against each other sends seismic waves rippling across earth’s surface
Some critics of the impact theory have put forward that the impact precedes the mass extinction by about 300,000 years and thus was not its cause. [ 209 ] [ 210 ] However, in a 2013 paper, Paul Renne of the Berkeley Geochronology Center dated the impact at 66.043 ± 0.011 million years ago, based on argon–argon dating .
Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...
